I can recollect my own fresh installs from ISO, in certain cases they never booted by normal meanings. Wrong partitioning, missing bootloader, etc.

I am not sure what help you might want in this case. If it is a testing system you might either re-install and see whether the issue re-occurs, or troubleshoot the boot process typing booting commands manually.
